Reef Chemistry Question of the Day [HASHTAG]#134[/HASHTAG]
I thought we'd try something different today and for the next few follow up questions.
This topic is not something I expect many people to know, but which is a neat fact to learn. So in picking an answer, if you explain your logic it might be interesting to other readers....
The movement of molecules through water and air is critical for a reef tank. Bringing O2 to organisms, for example, or removing CO2.
In order to have a good understanding of these processes, we need to understand how molecules move.
The simplest case is a gas (air) so we'll start there in this first question.
Molecules in air are constantly bouncing around off each other and off objects like you or a table. In between bounces they move in a perfectly straight line.
How fast do you think the molecules of O2 in the air in your home are typically moving between bounces (on average)?
A. 0.1 mile per hour
B. 1 mile per hour
C. 10 miles per hour
D 100 miles per hour
E. 1,000 miles per hour
F. 186,000 miles per second
Good luck!
